Biological Activity

[Description]:

SB-3CT is a potent and competitive inhibitor of matrix metalloproteinase (MMP-2) and MMP-9.

Research Areas >> Cancer

[Target]

MMP-2, MMP-9[1]

[In Vitro]

SB-3CT has shown efficacy in an animal model of severe traumatic brain injury (TBI). SB-3CT inhibits MMP-9 with an inhibition constant Ki of 400±15 nM[1]. Inhibition of PC3 tumor growth by SB-3CT could also be a direct consequence of reduced extracellular matrix degradation within the bone tissue by the tumor cells themselves and/or by osteoclasts. Indeed, SB-3CT treatment is associated with a reduced osteolytic response, indicating that SB-3CT helps to preserve bone integrity[2].

[In Vivo]

Post-ischemic treatment with SB-3CT significantly diminishes brain damage and reduced infarct volume to about 20% of the total hemisphere. SB-3CT treatment ameliorates neurobehavioral outcomes, particularly in the motor and sensory functions[3].

[Cell Assay]

PC3 cells are seeded in 35-mm dishes (5×104 cells/dish) in complete culture medium. The next day, the medium is replaced with complete medium supplemented with 1% DMSO alone (vehicle) or SB-3CT (final concentrations 0.1-50 μM) in 1%DMSO. At various times, the cells are harvested with trypsin and counted[2].

[Animal admin]

Adult male C57Bl/6 J mice, 6-9 weeks of age and weighing 20-28 g are divided into four groups: vehicle-treated group and SB-3CT-treated one with treatment for either one day or seven days after embolic MCA occlusion. SB-3CT (12.5 mg/mL) is freshly dissolved in 25% DMSO/65% PEG-200/10% water and filtered through an Acrodisc syringe filter with a 0.2 μm, 13-mm diameter sterile hydrophobic PTFE membrane. Mice are ip injected with 2 μL/gram body weight of this solution (equivalent to 25 mg/kg) 2 hours after embolic ischemia, followed by an additional dose at 4 hours. In repeated-dose treatment conditions, the same dose of SB-3CT is ip administered 2 and 4 hours after embolic ischemia, followed by once daily from post-ischemia day 1 to 6. Earlier work indicated that ip administration of SB-3CT does not alter mean arterial blood pressure, pH, PCO2, and PO2.
